Tailored heavy-duty continuous mechanical screw unloaders engineered to operate across high humidity, river basins, and ocean ports across Brazil.
Brazil stands as the largest consumer and producer of cement in Latin America, driven by landmark initiatives such as the Novo PAC (Growth Acceleration Program), large-scale residential construction, and intensive coastal and riverine logistics developments. From the bustling maritime gateways of Port of Santos, Port of Paranaguá, Port of Itaqui, and Port of Suape to inland waterway hubs along the Amazon and Madeira River corridors (such as Manaus, Santarém, and Barcarena), the demand for continuous, rapid bulk powder discharging has reached unprecedented levels.
Traditional grab cranes and outdated pneumatic unloader systems in Brazil face severe challenges, including high energy consumption, severe dust pollution, material loss during monsoon downpours, and strict compliance scrutiny by Brazil's environmental agency (IBAMA) and local port authorities (ANTAQ). As Brazilian cement conglomerates and port terminal operators seek clean, cost-efficient, and fully automated operations, our modern continuous screw ship unloaders provide the decisive competitive edge.
Tons per Hour Peak Discharging Capacity for Large Bulk Carriers
Dust Spillage with Hermetically Sealed Vertical Screw Systems
Reduction in Electrical Energy Usage vs Traditional Vacuum Unloaders
Continuous AI-Monitored Automated Material Feed Control
Designed to thrive in Brazil's tropical climate, marine salinity, and demanding high-throughput supply chains.
Our screw flights feature proprietary tungsten-carbide surfacing and specialized alloy linings designed to resist the abrasive nature of clinker, raw cement, and high-silica powders under Brazilian coastal humidity.
Equipped with intelligent load-sensing feeder heads and variable-frequency drives (VFD) that automatically adjust torque and feed depth based on cargo density, preventing pipeline clogging and maximizing constant capacity.
Whether navigating fixed finger piers in the Amazon basin or expansive rail-bound quaysides in Santos, our comprehensive portfolio offers portal rail, stationary pivot, and steerable rubber-tyre mobility.
We specialize in providing overall solutions for bulk material transfer, storage, and transportation systems, as well as the R&D, design, manufacturing, and sales of high-end loading and unloading equipment for powdery and granular bulk materials across Brazil and international markets.
The company's products and services have been exported to countries such as Australia, Korea, Singapore, the Philippines, Vietnam, Malaysia, Indonesia, Sri Lanka, and Russia, earning widespread acclaim and setting new benchmarks for Brazilian infrastructure partnerships.
Over the past two decades, AOTUO has dedicated itself to the research, development, and manufacturing of screw ship unloaders, becoming a benchmark for "Chinese products replace imports." Along the Yangtze River and other inland riverbanks, as well as in seaports and docks, its unloading equipment has been deployed across more than twenty provinces in China and globally across key Latin American, Asian, and Oceanian trade hubs. Its comprehensive manufacturing and lifecycle service system has earned widespread acclaim from Brazilian port authorities, EPC contractors, and bulk cement logistics operators.
